values for the commands, compared to the internal command values
(HAL_ANI_CMD.)
My eventual aim is to make the HAL_ANI_CMD internal enum match
the public API and then remove all this messiness.
This now allows HAL_CAP_INTMIT users to use a public HAL_CAP_INTMIT_
enum rather than magic constants.
The only magic constants currently used by if_ath are "enable" and
"present". Some local tools of mine allow for direct, manual fiddling
of the ANI variables and I'll convert these to use the public enum API
before I commit them.
